Adrienne Maloof knows how to keep it professional and put on a brave face.

And that's exactly what the Real Housewives of Beverly Hills star did last night during her first public appearance since news broke that Paul Nassif—Adrienne's husband of 10 years—legally filed for separation.

The stunning celeb—who looked gorgeous and slim in a curve-hugging dress (sans wedding ring)—opened up about how she's feeling in the wake of the split at Wednesday night's L.A. launch of the OMG iPhone case at Kitson.

"It's always difficult,"Maloof said with a heavy sigh when asked how she feels about the upcoming RHWBH season. "Even if you've had those relationships that have been difficult before and you've maybe mended those relationships, it's tough to relive it. That's what makes it difficult."

Although Adrienne's split will indeed be documented on television, the reality star is focusing on her kids—Gavin, 9, and 6-year-old twins Colin and Christian—and doesn't have any regrets filming the show:

"My priority has always been my children. They have always been first in my life," the 50-year-old star said. "But I have to say it's been tough, it's been trying, this season has been a little difficult for me but again I did the show because Bravo has given me a great platform for my work."

She continued, elaborating that the media attention is tough on the entire family, "You know my family's been in the public eye but when you're in it on such a grand scale, I don't really think you know what you're getting into until you're in it and then, you know, you deal with it."

And Adrienne's certainly proud of the way her children have handled the news:

"They're fantastic. My children are the best. They're lovely, well adjusted…and I'm blessed to have them."

What a great mom! We wish the whole family all the best during this trying time.
